TL;DR: In this paper, an extensive experimental study was carried out to analyse the post-heating characteristics of concretes subjected to temperatures up to 800°C. Major parameters of the study were the slag content of cement (0, 16, 25, 41 or 66 m%) and the value of maximum annealing temperature.

TL;DR: In this paper, the influence of various types of cements on the behavior of concrete at high temperatures was analyzed. But the main focus of the study was on the effect of pozzolanic additives on the heat resistance properties of concrete.

TL;DR: In this paper, a few Hungarian soils which are identified as dispersive are examined with geotechnical, agricultural and phase analytical methods, and the results show that the dispersive behavior is related to the physico-chemical composition of the soil, therefore the application of these kind of clays in flood protection structures, like dikes cannot be considered as a solution for the seepage problems.

TL;DR: In this paper, three different assessment methods were used to study the behaviour of the material: (1) determination of ash content, (2) flame propagation test and (3) thermal analysis.

TL;DR: In this article, a series of extensive experimental studies were conducted to evaluate the chloride ion binding capacity of tested concrete cements in decreasing sequence, and the results indicated that the increasing substitution of clinkers by GGBS improves the chloride resistivity in concrete made with the same water to cement ratio.
